+# As of 2020-12-19, there are 3 error messages:
+#
+#      make: "(stdin)" line 2: Zero byte read from file
+#      make: "(stdin)" line 2: Unexpected end of file in for loop.
+#      make: "(stdin)" line 3: Zero byte read from file
+#
+# The one about "end of file" might be misleading but is due to the
+# implementation.  On both errors and EOF, ParseGetLine returns NULL.
+#
+# The one about the "zero byte" in line 3 is surprising since the only
+# line that contains a null byte is line 2.
